Hi, i brought a 01 dhi frame with the chainguide and i am not sure how it mounts. There is two parts to it, one with the rollers and the metal disc. THe disc has five holes and i noticed that some crankarms also have fiive arms sticking out of them with holes. Also a lot of chainrings have five holes. It all bolts together right? The other thing i am confused about is how do i mount the part with the rollers? Pics of that area would be very much appreciated.
